Minimize Products and Algorithms

As for all Sentinel missions, the Sentinel-5P products are freely available to users. After the commissioning phase (6 months after launch), data will be gradually available to the public via the Copernicus Open Access Hub.


Level 1B – User technical documentation

The information needed to properly use the Level 1B data can be found on Table 1:

  • IODS (Input Output Data Specification): description of the products that are the result from the Level 0 to Level 1b processing
  • ATBD (Algorithm Theoretical Basis Document): high level description of the algorithms used in the Level-0 to 1b data processing
  • PRF (Product Readme File): description of changes between different product versions and overall quality information (available a few months after launch)

Level 2 – User technical documentation

The information needed to properly use the Level 2 data can be found on Table 2:

  • PUM (Product User Information): information on the technical characteristics of the S5P/TROPOMI Level 2 products
  • ATBD (Algorithm Theoretical Basis Document): detailed information on the retrieval algorithms
  • IODD (Input Output Data definition): description of the input and output data of the S5P/TROPOMI Level 2 processing
  • PRF (Product Readme File): description of changes between different product versions and overall quality information (available few months after launch)

More documents are available on the S5P document library.
